a piece of writing, a painting, or something with a design (see attestations); the initial "i" on this word drops away before tla-, as in tlacuilolli, which has probably contributed to the evolution of the word cuilolli
See an image that represents cuilolli from the simplex glyph Cuilol in the Visual Lexicon of Aztec Hieroglyphs, ed. Stephanie Wood (Eugene, Ore.: Wired Humanities, 2020-present).
'tlahtohchîmalli ihcuilôlli' = le bouclier royal décoré de motifs = the royal shield decorated with patterns
See the Visual Lexicon of Aztec Hieroglyphs for examples of the Cuilol (an apocopation of cuilolli) or icuilolli personal name glyph. https://aztecglyphs.wired-humanities.org/fulltext-quick-search?search_ap...
